Title: Apparatus for removal of phosphorus in sewage
Inventor: FURUHATA YOSHIMASA
IPC: C02F1/58
Filed: 1984-03-13
Abstract: PURPOSE:To remove phosphorus or SS with good efficiency, by arranging a filter material comprising phosphate mineral to an upper layer and arranging a filter material layer for removing a solid substance to a lower layer while providing an alkali injection port to the upper surface of the lower filter material layer or in the upper filter material layer. CONSTITUTION:Water to be treated with pH of 8.5-9.5 containing 50-60mg/l of Ca is introduced into the lower part of a filter material layer 3 from a supply pipe 1 through an inflow pipe 2 and upwardly flowed through the filter material layer 3 to remove SS therein during the passage through said layer 3. The SS removed water is guided to a dephosphorization material layer 4 while alkali is supplied from an alkali supply pipe 7 through an alkali injection pipe 6 during this period to adjust the pH of the SS removed treated water to a range suitable for dephosphorization. In this case, it is pref. to regulate the addition amount of alkali while the pH of water to be treated is detected and the pH controlled water to be treated is subsequently passed through a filter material layer comprising phosphate mineral and contacted therewith to remove phosphorus.
